ICE
Oh Well
California requires that smoke alarms have a ten year battery that can't be replaced. The alarms are expensive but won't start chirping for ten years... or so the manufacturers claim.
Not that I can find.Is the 10 year battery option in the IRC?
I wish I had a built-in market for repeat customers like that!I believe the manufactures recommend replacing the whole detector within ten years.
in case the regular power supply to the smoke alarm is interrupted, be provided with a battery as an alternative power source that can continue to provide power to the smoke alarm for a period of no less than 7 days in the normal condition, followed by 4 minutes of alarm.
